Description

Technical Field

[0001] The utility model is applicable to the field of communication antennas and provides a shark fin combined antenna. Background Art

[0002] The shark fin combined antenna is a multi-functional antenna system widely used on vehicles, ships and fixed devices. Its design aims to integrate multiple wireless communication functions, such as broadcasting, satellite positioning, wireless network and mobile communication, etc., to provide an integrated solution. By integrating multiple communication frequency bands and protocols into one, the shark fin combined antenna can improve the communication ability and usability of the device without adding additional antennas.

[0003] The principle of the shark fin combined antenna is based on embedding multiple independent antenna elements into a streamlined housing. Each antenna element is responsible for receiving or transmitting signals of a specific frequency band, and the entire combined structure realizes the effective reception and transmission of signals of different frequencies through optimized design. These antenna elements perform signal processing and conversion through an internal distributor and feeder system, so that all antennas can operate under a unified interface. Its unique shape not only has good aerodynamic performance, but also can effectively minimize signal interference.

[0004] However, the connecting wires inside the current shark fin combined antenna often shake due to vibration and movement, which may cause wear and damage to the connecting wires. The stability of the connecting wires directly affects the overall performance of the antenna. When the connecting wires are damaged or there are problems with the interfaces, the communication function of the antenna will be significantly reduced, affecting the reception and transmission of signals.

A nut is threadedly connected to the limiting stud.

[0006] Further, the position of the reserved bayonet corresponds to the position of the reserved port on the limiting stud.

[0007] Further, the limiting sleeve is made of plastic material, and the edges and corners of the limiting sleeve are treated with rounded corners for smoothness.

[0008] Further, a number of downwardly extending mounting posts are fixedly connected inside the housing. The gasket is provided with screw holes corresponding to the mounting posts one by one, and the gasket is detachably connected by screws passing through the mounting posts and the screw holes.

It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0022] See Figures 1-4 , the purpose of the present utility model is to provide a shark fin combined antenna, which includes a housing 1 in the shape of a shark fin streamline. The bottom of the housing 1 is open and the inside is hollow. The housing 1 is made of hard plastic material. A gasket 2 is fixedly connected to the bottom of the housing 1. A zinc base 3 is installed on the gasket 2. The zinc base 3 is provided with a through hole 31. A limit stud 5 is fixedly connected to the bottom of the zinc base 3. The limit stud 5 is hollow inside and communicates with the through hole 31. The limit stud 5 is provided with a reserved opening 51. The reserved opening 51 is vertically arranged on the limit stud 5 and penetrates the front side of the limit stud 5. The reserved opening 51 can allow a signal line to pass through.

[0023] A limit sleeve 6 is sleeved on the limit stud 5. One side of the top of the limit sleeve is provided with a semi-circular reserved bayonet 62. A nut 7 is threadedly connected to the limit stud 5. The nut 7 is a hexagonal nut. Specifically, during installation, first, the limit sleeve 6 is sleeved on the limit stud 5, and then the nut 7 is rotated on the limit stud 5. During the rotation process, the nut 7 drives the limit sleeve 6 to move upward.

[0024] This device is equipped with four groups of signal connectors, namely: a first connector 412 connected by a first connecting wire 411, a second connector 422 connected by a second connecting wire 421; a third connector 432 connected by a third connecting wire 431; a fourth connector 442 connected by a fourth connecting wire 441. One ends of the four groups of connecting wires away from the connectors are all installed inside the housing 1 as the ends for receiving and transmitting signals. The four groups of connecting wires are heat-shrink bundled through heat-shrink tubes, and after being bundled into a main wire, they pass through the through-hole 31 of the gasket 2.

[0025] Preferably, the position of the reserved bayonet 62 corresponds to the position of the reserved opening 51 on the limit stud 5.

[0026] Preferably, the limit sleeve 6 is made of plastic, and the edges of the corners of the limit sleeve 6 are treated with rounded corners for smoothness.

[0027] Preferably, a number of downward mounting posts 11 are fixedly connected inside the housing 1, and the gasket 2 is provided with screw holes corresponding to the mounting posts 11 one by one. The gasket 2 is detachably connected by screws passing through the mounting posts 11 and the screw holes.

[0028] Preferably, the peripheral edges of the gasket 2 are in contact with the inner surface of the housing 1, which can achieve a good sealing effect.

[0029] Preferably, a number of convex teeth 61 are fixedly connected to the limit sleeve 6, and a number of notch parts corresponding to the convex teeth 61 one by one are provided on the top of the zinc base 3. The convex teeth 61 can be embedded into the notch parts, so that the position of the reserved bayonet 62 always corresponds to the position of the reserved opening 51 on the limit stud 5.

[0030] In summary, in the actual production and manufacturing process, first pass the signal wire through the through-hole 31 of the zinc base 3, then sort out the signal wire, use a heat-shrinkable rubber tube to bundle the signal wire into a main wire, then install the ends for sending and receiving signals of the signal wire on the housing, then fixedly connect the gasket 2 and the housing 1 by screws, then bend the main wire of the signal wire into the reserved opening 51 of the limit stud 5, sleeved the limit sleeve 6 on the limit stud 5, tighten the nut 7, the main wire of the signal wire passes through the reserved bayonet 62, and the limit sleeve 6 clamps the main wire of the signal wire to complete the fixation of the main wire of the signal wire.

[0031] Thus, this device is not only simple in processing and installation and easy to operate, but also can reliably fix the main wire of the signal wire. It prevents the connecting wires inside the shark fin combined antenna from shaking due to vibration and movement, and reduces the wear and damage of the connecting wires. The stability of the connecting wires directly affects the overall performance of the antenna. This solution slows down the damage of the device and is reliable and durable.

[0032] Of course, the present utility model may also have many other embodiments.
